Sharing wifi connection to ethernet port on pi3 b+

Hi, I’ve read all the tutorials possible on stackexchange on how to use ARP to share my pi wifi to the ethernet port (in order to give wireless capabilities to an ethernet-only device, essentially emulating what the little chinese rj45 dongles like the Vonets VAP11G 300 are doing.

I think (I’m not sure) that because dietpi is so slim, it’s missing quite a bit of the stack required to follow tutorials like this one: https://raspberrypi.stackexchange.com/questions/88954/workaround-for-a-wifi-bridge-on-a-raspberry-pi-with-proxy-arp/88955#88955. Specifically, things like modifications to /etc/avahi/avahi-daemon.conf do not work because well, the file is missing.

I’ve spent days trying to make this work and I finally must admit defeat - It’s frustrating because the opposite way around is trivial in dietpi with the AP (hotspot) software install. So i’m sure it’s possible, I just don’t know how to do it. And I hate to have to run mate experimental and all the bloat it brings to what is essentially an headless server.

Has anyone achieved this before or knows how to do it on a dietpi distro? Thank you so much!

You can simply install Avahi Daemon: G_AGI avahi-daemon

Yeah our own implementation works only the other way round, sharing an Ethernet connection via WiFi as WiFi Hotspot. It is on the roadmap to be more flexible there. But aside from that you can follow any guide for Debian to setup network. In case as above you need to install required APT packages.

thanks, will try that!
